Abstract

A production sleeve assembly for use downhole comprises a fluid pathway configured to provide fluid communication between an exterior of a wellbore tubular and an interior of the wellbore tubular, a flow restriction disposed in the fluid pathway, and a valve disposed in series with the flow restriction in the fluid pathway. The valve comprises: a rupture disk and a plug releasably engaged in the fluid pathway in series with the rupture disk. The valve is configured to allow production from the exterior of the wellbore tubular to the interior of the wellbore tubular through the chamber without producing past the plug once the rupture disk is actuated.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A production sleeve assembly for use downhole comprising:
 a fluid pathway configured to provide fluid communication between an exterior of a wellbore tubular and an interior of the wellbore tubular through a chamber; 
 a flow restriction disposed in the fluid pathway parallel to the axis of the wellbore tubular; and 
 a valve disposed in series with the flow restriction in the fluid pathway, wherein
 the valve comprises: 
 a rupture disk; and 
 a plug releasably engaged in the fluid pathway in series with the rupture disk, wherein the valve is configured to allow production from the exterior of the wellbore tubular to the interior of the wellbore tubular through the chamber and past the plug once the rupture disk is actuated; wherein the valve comprises a flowpath that is perpendicular to the axis of the wellbore tubular, wherein the rupture disk initially traps the plug in the valve. 
 
 
     
     
       2. The assembly of  claim 1 , wherein the flow restriction comprises an autonomous inflow control device. 
     
     
       3. The assembly of  claim 1 , wherein the plug comprises a ball. 
     
     
       4. The assembly of  claim 1 , wherein the valve is configured to release the plug when the rupture disk is ruptured and the pressure within the exterior of the wellbore tubular is greater than the pressure within the interior of the wellbore tubular. 
     
     
       5. The assembly of  claim 1 , wherein the plug is configured to at least partially disintegrate or at least partially dissolve in response to a fluid flow through the chamber. 
     
     
       6. The assembly of  claim 1 , wherein the rupture disk comprises a frangible material. 
     
     
       7. The assembly of  claim 1 , further comprising a seat, wherein the plug sealingly engages the seat. 
     
     
       8. The assembly of  claim 7 , wherein the seat, the chamber, and the plug comprise a ball type check valve. 
     
     
       9. The assembly of  claim 7 , wherein the seat comprises a weep hole, and wherein the weep hole is configured to provide choked fluid communication past the plug. 
     
     
       10. The assembly of  claim 7 , wherein the seat creates a restriction to flow in addition to that created by the flow restriction. 
     
     
       11. The assembly of  claim 7 , wherein the seat is configured to at least partially erode in response to a production flow from the exterior of the wellbore tubular into the interior of the wellbore tubular. 
     
     
       12. A method of changing the flow state of a production sleeve comprising:
 pressurizing an interior of a wellbore tubular to a first pressure, wherein the first pressure is greater than a second pressure in an exterior of the wellbore tubular; 
 actuating a rupture disk in response to the first pressure, wherein the rupture disk is disposed in a fluid pathway between the exterior of the wellbore tubular and the interior of the wellbore tubular; 
 maintaining the first pressure within the interior of the wellbore tubular using a plug, wherein the plug is releasably engaged in the fluid pathway adjacent the rupture disk; 
 decreasing the pressure in the interior of the wellbore tubular below the second pressure; and 
 establishing fluid communication between the exterior of the wellbore tubular and the interior of the wellbore tubular along the fluid pathway through a first flow restriction in the fluid pathway in response to the decreasing of the pressure in the interior of the wellbore tubular, wherein the first flow restriction is parallel to the axis of the wellbore tubular, wherein the plug and the rupture disk form a valve with a flowpath that is perpendicular to the axis of the wellbore tubular, and wherein the rupture disk initially traps the plug in the valve and prevents flow across the valve, and wherein the valve becomes a one-way valve after actuating the rupture disk. 
 
     
     
       13. The method of  claim 12 , further comprising;
 maintaining the first pressure within the interior of the wellbore tubular using the one-way valve, wherein the one-way valve is configured to allow fluid flow from the exterior of the wellbore tubular to the interior of the wellbore tubular while substantially blocking flow from the interior of the wellbore tubular to the exterior of the wellbore tubular; and 
 bypassing a second flow restriction in the fluid pathway downstream of the one-way valve. 
 
     
     
       14. The method of  claim 12 , further comprising:
 actuating a second rupture disk in response to the first pressure, wherein the second rupture disk is disposed in a second fluid pathway between the exterior of the wellbore tubular and the interior of the wellbore tubular; and 
 establishing fluid communication between the exterior of the wellbore tubular and the interior of the wellbore tubular along the second fluid pathway in response to the decreasing of the pressure in the interior of the wellbore tubular. 
 
     
     
       15. The method of  claim 12 , wherein the plug is releasably engaged with a seat in the flowpath of the valve. 
     
     
       16. The method of  claim 15 , further comprising:
 flowing a fluid from the exterior of the wellbore tubular to the interior of the wellbore tubular along the fluid pathway; and 
 eroding at least a portion of the seat in response to the fluid flowing through the fluid pathway. 
 
     
     
       17. The method of  claim 15 , wherein the seat creates a restriction to flow in addition to that created by the first flow restriction. 
     
     
       18. The method of  claim 12 , further comprising:
 flowing a fluid from the exterior of the wellbore tubular to the interior of the wellbore tubular along the fluid pathway; and 
 eroding at least a portion of the plug in response to the fluid flowing through the fluid pathway. 
 
     
     
       19. The method of  claim 12 , further comprising:
 removing substantially the entire rupture disk from the fluid pathway in response to actuating the rupture disk.
